with Seti and every other subject that deals with finding "design", we are able to pinpoint a location of the source of design. With Seti we would be able to name a star system and a time frame of when the intelligent message was sent, and while we may not be capable of finding out who sent it, it's still a physical possibility that we could.

In every single field that deals with design, we can also find the when, where, how, and even the who. ID is the only field that has no method whatsoever of finding the when, where, how and even the who of what they considered to be an intelligenct cause. This is what happens when you propose supernatural explanations that lead absolutely no where. ID can't be compared to SETI because of this.
